How to distinguish virtual currency from public chain

1.

what is digital currency

digital currency can be used to describe all electronic currencies, including virtual currency and cryptocurrency. Digital currency is a kind of electronic currency without any physical form. Because of its functions and inherent attributes, it is the same as the standard illegal fixed currency, and can also be referred to as the network version of cash. Digital currency is invisible. People need to use and hold it through devices that can be connected to a specific network

T1: eth (the first public chain at present, the underlying platform of Shanzhai coin breeding, and in the speculation of eth2.0) EOS (community consensus + DAPP possible explosion + defi can also join + drop out of high cost performance) Zec (anonymous leader)

T2: Yas (UBI concept, low market value, great potential) atom (cosmos, advantage new public chain), XRP (the decline in 2019 has not risen, so the upward space is still very large) Polkadot dot (Boca, the goal is to surpass Ethereum) KSM (Boca pioneer)

T3: Ada (potential) NEO (myth of 1000 times of the last bull market), ont (strong village), Iost (Iost is currently undervalued, DAPP is also in good development)

there are platform coins in the coin circle, corresponding to HT, BNB, MX

2.

blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

3. The digital currency

issued based on Ethereum public chain should be observed according to the price trend of the platform.

4.

At present, whether a digital currency is a valuable currency basically belongs to the "angel wheel" stage. There are three criteria to determine whether a digital currency is a valuable currency: one is the team, the other is the economic model, and the third is the instry demand

The randomness of the

team is too great, so we will not discuss it here. This paper first makes a detailed analysis of the economic model of digital currency. In the following article, the author will analyze some digital currencies according to different instries

Strictly speaking, the economic model involved in this paper is not completely equivalent to the concept described in economics. Especially in digital currency, currency consensus mechanism and incentive mechanism

Consensus mechanism is the strategy and method for each node in the blockchain system to reach an agreement, which should be selected flexibly according to the different types of system and application scenarios

common consensus mechanisms include pow, POS, dpos, pbft (and its variants), etc. In addition, based on the different application scenarios of blockchain technology and the characteristics of various consensus mechanisms, this paper evaluates the technical level of various consensus mechanisms according to the following dimensions:

A) compliance supervision: whether super permission nodes are supported to supervise the nodes and data of the whole network

b) performance efficiency: the efficiency of reaching a consensus and being confirmed

Resource consumption: CPU, network input and output, storage and other computer resources consumed in the process of consensus

d) fault tolerance: the ability to prevent attacks and fraud

1 instry background

looking for Instry pain points: asset management needs professional team and knowledge, but now most digital currency investors do not have it; The fluctuation of digital money market is huge, and investors can't keep the value of assets in the falling market

2 own advantages

in the stock and futures markets for many years, has a mature and high-quality asset management team; AI big data team has strong technical strength

3 Market Research

after market research, it is estimated that the market value of asset management will be about US $1 billion in the next five years

4 total amount of digital currency

after considering the expected asset management market value, development cycle and difficulty, we will consider issuing 2 billion pieces of XT based on Ethereum erc20 digital currency, and never issue additional ones

5 allocation method

early stage investors hold 10%, teams hold 20%, business operation 10%, community construction 10%, and investors hold 50%

6 digital currency release / repo mechanism

the release mechanism can be divided into three categories:

the first category: the money holding part of business operation is fully unlocked, and the purpose is limited to business and operation activities

the second type: the release mechanism of community construction is that community members release exclusive information, cooperation platform release exclusive project progress and so on. According to the number of participating IDS, the corresponding proportion of XT is released (publishers and participants get 50% each) until all the releases are completed (after the release, the follow-up reward comes from the platform profit pool)

the third category: investors hold the mainstream digital currency, conct asset management in the platform, release a certain amount of XT according to the exchange ratio, and the early investors and the team hold part of it synchronously and unlock it according to the proportion

the repo mechanism is: 50% of the profit (in XT) will be returned to the holder; The rest goes into the platform profit pool, and 50% of XT in the profit pool is destroyed monthly until the total number of XT is 1 billion; The rest will be used as platform ecological construction fund

7 digital currency equity

profit sharing: holding XT is for platform users, and they can enjoy 50% of platform profits

platform Governance: participating in platform activities, enjoying XT awards and airdrop activities of other project parties

function customization: Based on platform AI big data, investors can purchase services optimized for indivial trading strategies

5.

Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:

1, open source code

upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public

2, complete decentralization

anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"

3. Developing decentralized applications

through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers

6. Virtual currency is a kind of blockchain technology. Some countries are legal, such as Japan, Russia, South Korea, etc. 66otc is currently the most fluent, reliable and best used OTC platform

7. There is no difference between true and false digital currency, and there is no difference between good and bad digital currency. Digital currency is just a tool, the key is to see who plays with it. Some people just use digital currency as a tool of pyramid selling, making money out of thin air, carrying out false propaganda and taking money away
if you don't understand digital currency, you'd better not touch it. The water of digital currency is very deep. Digital currency is even more chaotic, deception is repeated. If you are interested, you can first learn about the crowdfunding project token on coin Ying China platform.

8. 1. Mainstream currency, generally this kind of digital currency has been widely recognized by the market. In the process of implementation, it is strictly based on blockchain technology, but it has been used in practice. BTC and eth, which have good market liquidity, are mainstream currencies
2. Shanzhai coin is called Shanzhai coin because it has many similarities with mainstream coin in technical mode. Shanzhai coin also has its own real project, which is based on the underlying technology of blockchain and is implemented according to the plan of its white paper. The common counterfeit coins are EOS and BTM
3. Generally speaking, there is only one white paper that looks very strong. However, in the actual development, there may not be any procts or business landing. People just want to make money. However, the current laws and regulations have no way to take it, using formal means to achieve the goal of money. Hero chain, superstar, space chain and so on Welcome to the previous articles of chain horse: it has dropped from 2.6 yuan to 0.1449 yuan, breaking 18 times in six months, and the routine of air currency can't be prevented)
4. MLM currency, in the name of blockchain, has nothing to do with blockchain. The currency he issued can't be found on the Internet, and it's completely internal control. Usually, people will build their own trading platform, and then the K-line of the coin will always rise, telling investors that our future value will exceed bitcoin.

9. How to distinguish between real virtual goods ratio and pseudo finance? In the past two years, all kinds of financial management projects have been overwhelming, and fake finance with the word "currency" has emerged one after another. So how to distinguish real finance from capital disk, illegal collective financing and direct pyramid selling? The real virtual currency, economists think it is the ultimate currency of human beings, that is, the money that human beings ultimately use. Since it is money, it must have the following attributes at the same time:
1: decentralized (one technology: closed loop structure, source code permanently locked background; 2; After going to the center, there is no income subject, just like gold, which belongs to every participant)
2: no central processing unit (block connection)
3: third party open source (following the international practice of open source: third party open source, third party public trust, third party trusteeship)
4: quantitative issuance (resisting inflation)
5: third party matchmaking (no capital chain, no capital chain), Show the freedom and equality of money)
6: bonus system without distributing the principal of the recipient (recommending others to join, no recommendation award, no confrontation award, no sharing of the principal of the latecomer)
7: free registration, free access, no threshold at the bottom, no ceiling at the top (the same as bank deposits)
8: the price will fluctuate up and down e to the influence of the market There is no currency that goes up but doesn't go down.)
